乙酸/醋酸检测试剂盒介绍:
The Acetic Acid (ACS Manual Format) test kit is a simple method for the rapid and reliable measurement and analysis of acetic acid/acetate in foods, beverages and other materials.
Note for Content: The number of manual tests per kit can be doubled if all volumes are halved. This can be readily accommodated using the MegaQuantTM Wave Spectrophotometer (D-MQWAVE).
See our full range of organic acid test kits.

- No wasted ACS solution (stable suspension supplied)
- PVP incorporated to prevent tannin inhibition
- All reagents stable for > 2 years after preparation
- Very competitive price (cost per test)
- Mega-Calc™ software tool is available from our website for hassle-free raw data processing

。常用的膜一般是由乙酸纤维或硝酸纤维或此二者的混合物制成。近年来为适应制药和食品工业上灭菌的需要,发展了非纤维型的各向异性膜,例如聚砜膜、聚砜酰胺膜和聚丙烯腈膜等。这种膜在pH1~14都是稳定的,且能在90℃下正常工作。超滤膜通常是比较稳定的,若使用恰当,能连续用1~2年。暂时不用,可浸在1%甲醛溶液或0.2%叠氮化钠NaN3中保存。不同材质及截留分子量(MWCO)的超滤膜性能比较超滤膜相对流速(ml/min/cm2)性能特点聚醚砜,pH范围1~14 3,000 MWCO0.05肽的回收
